To all @QU/tom t may conc-em i f it lrnown that I, 4'loi-rv JLLOBRIEN, acitizen of the United Stategand,resident ,ot thecity of New. vYork,borough yofBroolrlyn, in the4 ycounty of KiIIgS 'aDClSte/L New York,have vinvented a new.l and .lm-

provedCheclr Protector', of which. the fol.

lowing' is a full, clear,'and exact description.

.My invention :relates to checlfprotectors, and aims to provide .certainnew and useful improvements in connection with a device of thischaracter, and more particularly over` the structure presented in mycopending application. j

lliiore particularly my present invention aims to provide a device ofthe character stated which Amay either be carried in the users pocket or:l'orm a part of a writing implement, it this is desired, so that thesame will be universally adaptable.

Further it is an object or" this invention to provide a check protectorwhich shall be Aextremely simple in construction and positive inoperation, and which also may bo used by the' operator in a prefectlynormal manner. j

Further objects of my invention will appear in the annexed specificationtaken in connection with the drawings which latter illustrate onepractical embodiment oi the same, and in which;

Figurel is a side view of my improved typeof check protector and showingthe same inuse.

Figures 27 3, ll and 5 are somewhat dia'- grannnatic views illustratingthe construction and disposition or" the respect to eachother. n

Figure 6 is sectional side view taken through the protector.

Figures 7 and 8 are sectional views taken alongl the lines 7 7 and 3-3and in the direction or the arrows indicated in Figure Il, and

, :Figure 9 is a sectional view taken along the lines 9-9 and in thedirection ot the Varrmvs indicated in Figure 6.

Referring now more particularly to F igure 6 it will be seen in theembodiment illustrated that the protector includes three main pieces, towit, a stem 10 of any desirable shape and material which is slidablyencircled by a sleeve 11 preferably having its parts one with exteriorJface knurled'as at-12, and a housing 13.

tion of the lt'will'jbe seen that the parts are retained assembled byvirtue of the fact thatft'he sleeves 12 carries a pair Vof pins 15;``the former riding in an angularly disposed slot 16 formed in thehousing 13 while the latter "projects into a-'slot 17 fformed inthefstem 10.

, urther 'the stem lO'is Vprovided witl'i'ja projecting portion 18'` thehead of `which Vis enlargedasat v19 and carriesa .pair of spaced ears 20'between 'which a toothed wheel 21 is rotatably mounted. lt will be seenthat the pin 15 preferably has its inner end eX-` tended to projectslightlybeyond the head 19. This will further'act to prevent anAaccidental detachment of the parts, and it will be understood that uponthe sleeve V1.1 being rotated .that any longitudinal movement of rre-lsgrarEIS Partnr n.IfFt@Ese :ron-N lrosrrn onRinN, or:enooxtvia:newfizoiair.V

this element with respect to the stem 10 will be precluded in that thepin l5 will simply Yride withinthe slot 17.

Further by virtue of the angular disposislot'lG, the pin 15 will causethe housing 13 spect to the stem 10 and by reason of the fact that thehousing 13 is formedwith an opening 22 it will be appreciated that thiswill resultin thefwheel 21 extending beyond this housing as in `Figurefl when said housing is retracted, and that the wheel 21 will becompletely enveloped as in Figures 5 and to move longitudinal with re-v6 upon the latter being projected., `Further i in this connection it isto be noted that a rotation. oi the housing 13 with respect to the stemlO'is prevented in that a longitudinal groove 24 is formed in one ofthese members, which groove acts 'as a guide for the pin 25 carried bythe second of the same.k

To now provide means which will permit of a person utilizing this devicein a normal manner it will be seen that the housing 13 has its forwardVend inclined as at 23.

Fromthe foregoing it will. be seen, attention being invited to Figure 1,that anoperator may hold the protector in a perfectly natural manner, inthat it is permissible to actuate the device while the same is held inan inclined position. j v

Thus all of the objects of my invention as set forth in the preamble orlthis specifica#V toothed iyheel carried by. saidr stern, ahous- Y ingsecured to said stern, andnnea-ns for4 effecting a positive projectionand retractiony Y toothed Wheel carried by said stem, a housing, asleeve encircling said stein and hous-v "lng, -for permitting saidhousing to bernoved of said housing With respect to` said stem.-
